"Muse Spark is available now, and Contemplating mode will be rolling out gradually in meta.ai."

How does one get their hands on these models? They are not open-source, right? I go to meta.ai, but it's just a chat interface---no equivalent to codex or claud code? Can you use this through OpenCode? Is meta charging for model access, or is the gathering of chat data a sufficiently large tithe?

"It will be available in private preview via API to select partners, and we hope to open-source future versions of the model."

I can't think of any "select partners" that would want to use this non-SOTA model. Just put it on OpenRouter.

		If Microsoft is a select partner, maybe they could shove it into Copilot for VS or something, but yeah, I'm wondering the same, maybe Apple could be one of their partners too?

That would be my question also. I like it when companies have easy to sign up for, pay as you go models. Being able to buy $5 worth of tokens and get an API key - in less than a few minutes - is ideal.

TBD it seems. So far the only explained usage pattern is through a Meta product (Whatsapp, Facebook, Instagram).

So to verify their claims and see how strong these models are, the answer is "believe us"?

Note: I'm expressing some skepticism here largely due to how recent rollouts from Meta flopped. Sincerely hoping that they do better this time around!

		I assume the answer is try it out in the chat mode? You could run your usual benches through that right

I appreciate that they build this stuff for their own benefit, but I don't want to feed even more of my private info. Hopefully the models will become public or lead to equivalent models from other sources.
